The slide plate 11 is fixedly connected to the right side of the driving rod 12 by welding, and the rear side of the auxiliary rod 10 is rotatably connected to the front side of the slide plate 11 through a rotating shaft.

[0033] By means of the above mechanism: through the motor 5, it is convenient to drive the transmission wheel 6 to rotate and drive the push shaft 8 to rotate, which is convenient to drive the hollow rod 9 to rotate back and forth. When the hollow rod 9 rotates, it can drive the auxiliary rod 10 to move, thereby driving the slide plate 11 to move. The slide plate 11 can push the driving rod 12 to make the scraper 13 move back and forth laterally. The scraper 13 is used to crush and spread the material agglomerated on the top of the screen 3 for material discharge. At the same time, the rotation of the rotating sleeve 15 can drive the connecting rod 17 to rotate and make the rubber wheel 18 rotate.

[0038] Working principle: in actual use, when concrete needs to be mixed, by starting the motor 5, the output shaft of the motor 5 rotates to drive the transmission wheel 6 on the right to rotate, and when the transmission wheel 6 on the right rotates, the transmission wheel 6 on the left can be driven to rotate. At this time, the push shaft 8 rotates and pushes the hollow rod 9 to rotate. The reciprocating rotation of the hollow rod 9 can drive the auxiliary rod 10 to follow the movement.

When the rotating sleeve 15 rotates, it will drive the connecting rod 17 to rotate. At this time, the rubber wheel 18 follows the movement and contacts the bottom of the screen 3. When the rubber wheel 18 collides with the screen 3, it will push the connecting rod 17 to move. At this time, the connecting rod 17 will compress the spring 16 to make the connecting rod 17 slide toward the inside of the rotating sleeve 15. The two rubber wheels 18 rotate and reciprocate to hit the bottom of the screen 3, causing the screen 3 to vibrate, thereby accelerating the material discharge speed. Through the cooperation of the scraper 13 and the rubber wheel 18, the screen 3 is prevented from being blocked and the material discharge is accelerated.
